Filters

PFCam's filter wheel holds up to 6 filters.
Filters should be requested on the telescope time application. Filters may be
changed from one night to the next, but changing filters during the night
is discouraged.

As of March 2008, the following 4" x 4" broad-band photometry filters
are available for PFCam:

The old set of similar 3" x 3" broad-band filters is still available,
however their use is discouraged as they cause some vignetting and
limit the field of view to about 10 x 10 arcminutes. Some of the 3"
filters are damaged and should not be used.
